46	=item selection (enabled by default)
47
48	(More) intelligent selection. This extension tries to be more intelligent
49	when the user extends selections (double-click and further clicks). Right
50	now, it tries to select words, urls and complete shell-quoted
51	arguments, which is very convenient, too, if your F<ls> supports
52	C<--quoting-style=shell>.
53
54	A double-click usually selects the word under the cursor, further clicks
55	will enlarge the selection.
56
57	The selection works by trying to match a number of regexes and displaying
58	them in increasing order of length. You can add your own regexes by
59	specifying resources of the form:
60
61	URxvt.selection.pattern-0: perl-regex
62	URxvt.selection.pattern-1: perl-regex
63	...
64
65	The index number (0, 1...) must not have any holes, and each regex must
66	contain at least one pair of capturing parentheses, which will be used for
67	the match. For example, the followign adds a regex that matches everything
68	between two vertical bars:
69
70	URxvt.selection.pattern-0: \\|([^|]+)\\|
71
72	Another example: Programs I use often output "absolute path: " at the
73	beginning of a line when they process multiple files. The following
74	pattern matches the filename (note, there is a single space at the very
75	end):
76
77	URxvt.selection.pattern-0: ^(/[^:]+):\
78
79	You can look at the source of the selection extension to see more
80	interesting uses, such as parsing a line from beginning to end.
81
82	This extension also offers following bindable keyboard commands:
83
84	=over 4
85
86	=item rot13
87
88	Rot-13 the selection when activated. Used via keyboard trigger:
89
90	URxvt.keysym.C-M-r: perl:selection:rot13
91
92	=back
93
94	=item option-popup (enabled by default)
95
96	Binds a popup menu to Ctrl-Button2 that lets you toggle (some) options at
97	runtime.
98
99	=item selection-popup (enabled by default)
100
101	Binds a popup menu to Ctrl-Button3 that lets you convert the selection
102	text into various other formats/action (such as uri unescaping, perl
103	evaluation, web-browser starting etc.), depending on content.
104
105	Other extensions can extend this popup menu by pushing a code reference
106	onto C<@{ $term->{selection_popup_hook} }>, that is called whenever the
107	popup is displayed.
108
109	It's sole argument is the popup menu, which can be modified. The selection
110	is in C<$_>, which can be used to decide wether to add something or not.
111	It should either return nothing or a string and a code reference. The
112	string will be used as button text and the code reference will be called
113	when the button gets activated and should transform C<$_>.
114
115	The following will add an entry C<a to b> that transforms all C<a>s in
116	the selection to C<b>s, but only if the selection currently contains any
117	C<a>s:
118
119	push @{ $self->{term}{selection_popup_hook} }, sub {
120	/a/ ? ("a to be" => sub { s/a/b/g }
121	: ()
122	};
123
124	=item searchable-scrollback<hotkey> (enabled by default)
125
126	Adds regex search functionality to the scrollback buffer, triggered
127	by a hotkey (default: C<M-s>). While in search mode, normal terminal
128	input/output is suspended and a regex is displayed at the bottom of the
129	screen.
130
131	Inputting characters appends them to the regex and continues incremental
132	search. C<BackSpace> removes a character from the regex, C<Up> and C<Down>
133	search upwards/downwards in the scrollback buffer, C<End> jumps to the
134	bottom. C<Escape> leaves search mode and returns to the point where search
135	was started, while C<Enter> or C<Return> stay at the current position and
136	additionally stores the first match in the current line into the primary
137	selection.
138
139	=item readline (enabled by default)
140
141	A support package that tries to make editing with readline easier. At the
142	moment, it reacts to clicking with the left mouse button by trying to
143	move the text cursor to this position. It does so by generating as many
144	cursor-left or cursor-right keypresses as required (the this only works
145	for programs that correctly support wide characters).
146
147	To avoid too many false positives, this is only done when:
148
149	=over 4
150
151	=item - the tty is in ICANON state.
152
153	=item - the text cursor is visible.
154
155	=item - the primary screen is currently being displayed.
156
157	=item - the mouse is on the same (multi-row-) line as the text cursor.
158
159	=back
160
161	The normal selection mechanism isn't disabled, so quick successive clicks
162	might interfere with selection creation in harmless ways.
163
164	=item selection-autotransform
165
166	This selection allows you to do automatic transforms on a selection
167	whenever a selection is made.
168
169	It works by specifying perl snippets (most useful is a single C<s///>
170	operator) that modify C<$_> as resources:
171
172	URxvt.selection-autotransform.0: transform
173	URxvt.selection-autotransform.1: transform
174	...
175
176	For example, the following will transform selections of the form
177	C<filename:number>, often seen in compiler messages, into C<vi +$filename
178	$word>:
179
180	URxvt.selection-autotransform.0: s/^([^:[:space:]]+):(\\d+):?$/vi +$2 \\Q$1\\E\\x0d/
181
182	And this example matches the same,but replaces it with vi-commands you can
183	paste directly into your (vi :) editor:
184
185	URxvt.selection-autotransform.0: s/^([^:[:space:]]+(\\d+):?$/:e \\Q$1\\E\\x0d:$2\\x0d/
186
187	Of course, this can be modified to suit your needs and your editor :)
188
189	To expand the example above to typical perl error messages ("XXX at
190	FILENAME line YYY."), you need a slightly more elaborate solution:
191
192	URxvt.selection.pattern-0: ( at .*? line \\d+[,.])
193	URxvt.selection-autotransform.0: s/^ at (.*?) line (\\d+)[,.]$/:e \\Q$1\E\\x0d:$2\\x0d/
194
195	The first line tells the selection code to treat the unchanging part of
196	every error message as a selection pattern, and the second line transforms
197	the message into vi commands to load the file.
198
199	=item tabbed
200
201	This transforms the terminal into a tabbar with additional terminals, that
202	is, it implements what is commonly refered to as "tabbed terminal". The topmost line
203	displays a "[NEW]" button, which, when clicked, will add a new tab, followed by one
204	button per tab.
205
206	Clicking a button will activate that tab. Pressing B<Shift-Left> and
207	B<Shift-Right> will switch to the tab left or right of the current one,
208	while B<Shift-Down> creates a new tab.
209
210	=item mark-urls
211
212	Uses per-line display filtering (C<on_line_update>) to underline urls and
213	make them clickable. When middle-clicked, the program specified in the
214	resource C<urlLauncher> (default C<x-www-browser>) will be started with
215	the URL as first argument.
216
217	=item automove-background
218
219	This is basically a one-line extension that dynamically changes the background pixmap offset
220	to the window position, in effect creating the same effect as pseudo transparency with
221	a custom pixmap. No scaling is supported in this mode. Exmaple:
222
223	@@RXVT_NAME@@ -pixmap background.xpm -pe automove-background
224
225	=item block-graphics-to-ascii
226
227	A not very useful example of filtering all text output to the terminal,
228	by replacing all line-drawing characters (U+2500 .. U+259F) by a
229	similar-looking ascii character.
230
231	=item digital-clock
232
233	Displays a digital clock using the built-in overlay.
234
235	=item example-refresh-hooks
236
237	Displays a very simple digital clock in the upper right corner of the
238	window. Illustrates overwriting the refresh callbacks to create your own
239	overlays or changes.
240
241	=item selection-pastebin
242
243	This is a little rarely useful extension that Uploads the selection as
244	textfile to a remote site (or does other things). (The implementation is
245	not currently secure for use in a multiuser environment as it writes to
246	F</tmp> directly.).
247
248	It listens to the C<selection-pastebin:remote-pastebin> keyboard command,
249	i.e.
250
251	URxvt.keysym.C-M-e: perl:selection-pastebin:remote-pastebin
252
253	Pressing this combination runs a command with C<%> replaced by the name of
254	the textfile. This command can be set via a resource:
255
256	URxvt.selection-pastebin.cmd: rsync -apP % ruth:/var/www/www.ta-sa.org/files/txt/.
257
258	And the default is likely not useful to anybody but the few people around
259	here :)
260
261	The name of the textfile is the hex encoded md5 sum of the selection, so
262	the same content should lead to the same filename.
263
264	After a successful upload the selection will be replaced by the text given
265	in the C<selection-pastebin-url> resource (again, the % is the placeholder
266	for the filename):
267
268	URxvt.selection-pastebin.url: http://www.ta-sa.org/files/txt/%
